What’s the LED lighitng LM80?

What is the LM80?It is the Illuminating Engineering Society of North America (IESNA) approved standard for measuring lumen maintenance of LED light sources.

LM-80-08 apply to the LED package, array, or module alone, not a complete system, it is testing a component level.

The standard does not provide guidance for extrapolation of testing results.

Who can perform testing?LM-80-08 testing should be performed by EPA recognized Laboratories.

Only reports from recognized laboratories are relevant. This standard is used for Department Of Energy (DOE) ENERGY STAR program early qualification in conjunction with other reports.

All the LED linear lighting product from Brandon Lighting use LED with available LM-80-08 test report from recognized laboratory.

LM-80 can be a useful tool for lighting professionals who are looking to analyze LED products; however, it is not a measure of LED system performance or reliability. It only describes how to measure how one part of an LED luminaire—the LED light source—performs over a period of time and under certain set conditions. Other components, including the LED optical system, heat sink, LED drivers and luminaire housing, should also be taken into consideration to form a full picture of an LED luminaire’s projected useable life. LM-80 is merely one critical part of a larger puzzle. LM-80 is also not a measure of the “lifetime” of a component or the LED lamps and luminaires that use that component. Unfortunately, LED component, lamp and luminaire manufacturers, among others, often use the data found in an LM-80 report to substantiate the “lifetime” claims of an LED product, even though that data alone cannot be used to predict the useful life of an LED product or system.

What LM80 can do for you more? While LM-80 doesn’t provide a full picture of a LED component’s long-term performance, it is an important part of the equation. LED Luminaire and lamp manufacturers, lighting designers and researchers should know how quickly the light output of an LED will depreciate to help them determine the useful lifetime of the product in which the LED will be used. They should also look at how the LED’s light output has degraded under the various temperature and current conditions, as well as how the color point has shifted at those same conditions. Those measurements will enable them to assess how the LED component is expected to perform under similar circumstances.
